Abstract
LA CORRELACION ENTRE UN PAR DE SEGMENTOS DE SEÑALES DIGITALES SE MIDE CON UN APARATO QUE INCLUYE UNA PLURALIDAD DE MULTIPLICADORES (1200). CADA UNO DE LOS MULTIPLICADORES GENERA EL PRODUCTO DE UNA MUESTRA RESPECTIVA DE CADA UNO DE LOS SEGMENTOS DE SEÑAL. LAS SALIDAS DE UNA PLURALIDAD DE CONVERTIDORES (1300) DIGITAL-ANALOGICOS (D/A) SE ACOPLAN A UN SUMADOR (80), MIENTRAS QUE CADA UNO DE LOS MULTIPLICADORES (1200) SE ACOPLA A LA ENTRADA CORRESPONDIENTE DE LOS CONVERTIDORES D/A (1300). EL SUMADOR (80) GENERA UNA SEÑAL DE SALIDA ANALOGICA IGUAL A LA SUMA DE LAS SEÑALES DE SALIDA ANALOGICA GENERADAS POR LA PLURALIDAD DE CONVERTIDORES D/A.CORRELATION BETWEEN A PAIR OF DIGITAL SIGNAL SEGMENTS IS MEASURED WITH AN APPLIANCE THAT INCLUDES A PLURALITY OF MULTIPLIERS (1200). EACH OF THE MULTIPLIERS GENERATES THE PRODUCT OF A SAMPLE REGARDING EACH OF THE SIGNAL SEGMENTS. THE OUTPUTS OF A PLURALITY OF DIGITAL-ANALOG CONVERTERS (1300) ARE COUPLED TO A SUMMER (80), WHILE EACH OF THE MULTIPLIERS (1200) IS COUPLED TO THE CORRESPONDING INPUT OF THE D / A CONVERTERS ( 1300). THE SUMADOR (80) GENERATES AN ANALOG OUTPUT SIGNAL EQUAL TO THE SUM OF THE ANALOG OUTPUT SIGNALS GENERATED BY THE PLURALITY OF D / A CONVERTERS.
